   I'd answer this somewhat differently.  The rocket jet would indeed
   dislodge the dust:  The particles
   would acquire velocities, and would follow mostly-parabolic paths and
   eventually collide with and stay
   on the surface again. While this might be labelled a "cloud", unlike in
   Earth's atmosphere these particles
    will presumably return to the Moon's surface in a few seconds, yet far
   away from the lunar lander.
    As to "why was thick dust still on the ground", most likely the dust
   was very thick.
   (many meters).

   "The lunar surface is covered by a layer of unconsolidated debris
   called the lunar regolith (fig. 53). The thickness of the regolith
   varies from about 5 m on mare surfaces to about 10 m on highland
   surfaces. The bulk of the regolith is a fine gray soil with a density
   of about 1.5 g/cm3 , but the regolith also includes breccia and rock
   fragments from the local bedrock (reviews by Heiken et al. 1974 and
   Papike et al. 1982). About half the weight of a lunar soil is less than
   60 to 80 microns in size. The grain size distribution is given in
   figure 55."
   There may be an additional factor.  As I vaguely recall, there is an
   odd electrostatic attraction
    between the particles of lunar soil.  Perhaps not surprising, because
   except for subsurface
   frozen-water deposits (and some polar craters) the moon is 'dry as a
   bone'.
